EXECUTIVE SUMMARY:
CVE-2026-42283 with a CVSS score of 7.7 is a vulnerability affecting the github.com/loft-sh/devspace package, specifically impacting its WebSocket implementation, which does not validate the source of incoming connections. This allows an attacker to establish a cross-origin WebSocket connection to the DevSpace UI server, enabling access to sensitive endpoints, including /api/logs to stream real-time pod logs, /api/enter to open an interactive shell inside a running pod, and /api/command to execute pre-defined pipeline commands. An attacker can exploit this vulnerability by visiting a malicious website while the DevSpace UI is running, requiring no special access or privileges, and gaining the capability to access and manipulate sensitive pod data. If exploited, this vulnerability could lead to unauthorized access and data exposure, compromising the security and integrity of DevSpace deployments, and potentially allowing an attacker to escalate privileges or disrupt critical operations. Prerequisites for exploitation include a malicious website and a user running the DevSpace UI with internet access, making it a significant business risk for organizations using DevSpace.[/subscribe_to_unlock_form]
